If you made a list of all the goals you have for yourself during and after college, from meeting new people to learning what interests you to getting started in a particular career, how many of them actually require that you attend one particular college?
More broadly, how many of them require that you attend a prestigious school?
And if those particular schools magically disappeared tomorrow, would you need to abandon your goals, or would you simply apply them at (by applying to) different schools.
Aim for the schools you want, sure. But remember that very few goals are dependent on a short list of colleges to help you achieve them.
